2.0
There are three memory blocks in each of the
PIC16F87X MCUs. The Program Memory and Data
Memory have separate buses so that concurrent
access can occur and is detailed in this section. The
EEPROM data memory block is detailed in Section 4.0.
Additional information on device memory may be found
in the PICmicro
(DS33023).

2.1
The PIC16F87X devices have a 13-bit program counter
capable of addressing an 8K x 14 program memory
space. The PIC16F877/876 devices have 8K x 14
words
PIC16F873/874 devices have 4K x 14. Accessing a
location above the physically implemented address will
cause a wraparound.
The RESET vector is at 0000h and the interrupt vector
is at 0004h.
